Description
Technical Field
The present invention relates to storage technologies, and in particular, to a method and an apparatus for storing video data.
Background
With the increasing diversification of cloud applications, videos have also entered the high definition era.
Compared with the common video data, the video data with high definition and large code stream can be stored for the same time length, and occupy more storage capacity.
Since the storage resources are usually limited in practical applications, it is desirable to find a way to store as much video data as possible without changing the storage capacity, so as to improve the utilization of the storage resources.
For this reason, the following solutions are proposed in the prior art: the video data storage capacity is reduced by defining a strategy, namely in the process of storing the video data, screening the data condition and judging the effectiveness of the trigger storage event, and the video data which does not accord with the screening condition and can not trigger the storage event can not be stored; the method is a way for reducing the amount of stored data from the source, and although the utilization rate of storage resources can be improved to a certain extent, the continuity and integrity of the data cannot be guaranteed.
Disclosure of Invention
In view of this, the present invention provides a method and an apparatus for storing video data, which can improve the utilization rate of storage resources and maintain the continuity and integrity of data.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a video data storage method, comprising:
creating a resource pool and setting the actual capacity of the resource pool;
storing the received video data into the resource pool before the actual capacity of the resource pool is occupied, and when it is determined that video data meeting transcoding conditions exist in the resource pool, transcoding the video data meeting the transcoding conditions and storing the transcoded video data into the resource pool.
A video data storage apparatus comprising:
the first processing module is used for creating a resource pool and setting the actual capacity of the resource pool;
and the second processing module is used for storing the received video data into the resource pool before the actual capacity of the resource pool is completely occupied, and transcoding the video data meeting the transcoding condition and storing the transcoded video data into the resource pool when the video data meeting the transcoding condition is determined to exist in the resource pool.
Therefore, by adopting the scheme of the invention, when the video data meeting the transcoding condition exists in the resource pool, the video data meeting the transcoding condition can be transcoded and then stored, and correspondingly, the video data not meeting the transcoding condition does not need to be transcoded, and compared with the video data before transcoding, the storage capacity occupied by the transcoded video data is less, so that more video data can be stored in the resource pool, and the utilization rate of storage resources is further improved; moreover, compared with the prior art, the scheme of the invention maintains the continuity and the integrity of the video data to the maximum extent.

Detailed Description
In order to make the technical solution of the present invention clearer and more obvious, the solution of the present invention is further described in detail below by referring to the drawings and examples.
Fig. 1 is a flowchart of a video data storage method according to an embodiment of the present invention. As shown in FIG. 1, the method comprises the following steps 11-12.
Step 11: a resource pool is created and the actual capacity of the resource pool is set.
Step 12: and before the actual capacity of the resource pool is completely occupied, storing the received video data into the resource pool, and when the video data meeting the transcoding condition is determined to exist in the resource pool, transcoding the video data meeting the transcoding condition and then storing the transcoded video data into the resource pool.
In practical applications, the resource pool may include only one sub-pool, or may include a plurality of sub-pools, for example, two sub-pools, which are described below for different situations.
One) resource pool only includes one sub-pool
How to create a resource pool is prior art. The resource pool has a virtualization feature, when storing video data, there is no need to care which storage device is stored on, and the specific physical device is transparent to the upper layer.
When the resource pool only includes one sub-pool, that is, the resource pool itself, and the sub-pool is not divided, the following processing is required to be further performed while the resource pool is created, in addition to the above-mentioned setting of the actual capacity of the resource pool: setting the expected capacity and the transcoding period of the resource pool; the actual capacity of the resource pool is duration Z (that is, video data which is not transcoded and has duration Z can be stored without considering the change of the code rate of the video data, etc.), the expected capacity of the resource pool is duration K, and the transcoding period of the resource pool is duration N.
When the actual capacity of the resource pool is fully occupied, the actual capacity occupied by the video data which is not transcoded is the duration N, the actual capacity occupied by the transcoded video data is the duration P, and the sum of the duration N and the duration P is equal to the duration Z.
The actual capacity occupied by the video data before transcoding corresponding to the transcoded video data with the actual capacity of the duration P is the duration M, the duration M is greater than the duration P, and the sum of the duration N and the duration M is equal to the duration K.
Specifically, before the actual capacity of the resource pool is fully occupied, the received video data is stored in the resource pool, and the following processing is periodically performed: calculating the difference between the current time and the duration N to obtain a time point a; determining the video data stored before the time point a as the video data meeting the transcoding condition, transcoding the video data meeting the transcoding condition and storing the transcoded video data into the resource pool, and deleting the video data meeting the transcoding condition from the resource pool, wherein the specific value of the period can be determined according to the actual requirement.
In addition, when the resource pool is created, the transcoding type can be further set; correspondingly, the video data meeting the transcoding conditions can be transcoded according to the set transcoding type, and the transcoded video data is stored in the resource pool.
The specific transcoding type can be determined according to actual needs, and the specific values of the duration Z, the duration K, the duration N, the duration P, the duration M, and the like can also be determined according to actual needs, but a certain relationship must be satisfied between them, for example, when the transcoding type is a frame extraction mode with a frame extraction rate of 1/3, there can be:
time length K-time length N × 1/3+ time length N ═ time length Z;
the time duration P is the time duration Z — the time duration N is the time duration M × 1/3.
For example, the following steps are carried out:
assuming that the value of the time length Z is 30 days, the value of the time length K is 40 days, the value of the time length N is 25 days, the value of the time length P is 5 days, the value of the time length M is 15 days, and the transcoding type is a frame extraction mode with the frame extraction rate of 1/3;
in addition, assuming that every 1 day passes, the difference between the current time and the time length N is calculated once to obtain a time point a, assuming that the current time is 29 days 0:00 every 4 months in 2014, and the time point a is 0:00 every 4 months in 2014, and accordingly, video data stored before 0:00 every 4 months in 2014 can be transcoded, that is, video data of the last 25 days is always reserved and not transcoded;
in this way, when the actual capacity in the resource pool is fully occupied, that is, the resource pool is full, 25 days of un-transcoded video data and 15 days of transcoded video data are stored in the resource pool, but the capacity actually occupied by the 15 days of transcoded video data is only equivalent to the 5 days of video data before transcoding, so that the purpose of storing 40 days of video data by using the resource pool with the capacity of only 30 days is achieved, and the utilization rate of storage resources is further improved.
In practical application, on the premise that the actual capacity of the resource pool is fixed, it is generally desirable to store video data for as many days as possible, and also desirable to have the proportion of the video data which is not transcoded in the stored video data as large as possible, because compared with the transcoded video data, the video data which is not transcoded has higher quality, so that the subsequent processing such as playback is more convenient; however, the greater the proportion of the video data that is not transcoded, the fewer the number of days the video data can be stored, and therefore, it is necessary to set the transcoding type and the above-described respective time periods appropriately to achieve an optimal balance between the two.
Two) the resource pool comprises two sub-pools
Regardless of the resource pool including several sub-pools, it is transparent to the outside, just one resource pool.
When two sub-pools are included in the resource pool, and it is assumed that the sub-pools are sub-pool 1 and sub-pool 2, the following processes are further required in addition to the setting of the actual capacity of the resource pool as described above while the resource pool is being created: setting the expected capacity of the resource pool and the actual capacity of each sub-pool; the actual capacity of the resource pool is duration Z, the expected capacity of the resource pool is duration K, the actual capacity of the sub-pool 1 is duration N, the actual capacity of the sub-pool 2 is duration P, and the sum of the duration N and the duration P is equal to the duration Z.
When the actual capacity of the resource pool is fully occupied, the video data which are not transcoded are stored in the sub-pool 1, and the video data which are transcoded are stored in the sub-pool 2.
The actual capacity occupied by the video data before transcoding corresponding to the transcoded video data with the actual capacity of the duration P is the duration M, the duration M is greater than the duration P, and the sum of the duration N and the duration M is equal to the duration K.
It can be seen that when the resource pool only comprises one sub-pool, the video data which is not transcoded and the video data which is transcoded are stored in the same resource pool and are transferred to the local pool, and when the resource pool comprises two sub-pools, the video data which is not transcoded and the video data which is transcoded are respectively stored in different sub-pools, and the two sub-pools are independent from each other, do not occupy the storage space of the other sub-pool and are transferred to the different pool.
Specifically, received video data may be stored into sub-pool 1 before the actual capacity of the resource pool is fully occupied; when the actual capacity of the sub-pool 1 is completely occupied and new video data is received, determining old video data to be covered by the new video data in the sub-pool 1 according to a preset cyclic covering rule, determining the old video data to be covered as the video data meeting the transcoding condition, transcoding the video data meeting the transcoding condition and storing the transcoded video data in the sub-pool 2, wherein the video data meeting the transcoding condition in the sub-pool 1 is covered by the new video data.
In addition, when the resource pool is created, the transcoding type can be further set; correspondingly, the video data meeting the transcoding conditions can be transcoded according to the set transcoding type, and the transcoded video data is stored in the sub-pool 2.
The specific transcoding type can be determined according to actual needs, and the specific values of the duration Z, the duration K, the duration N, the duration P, the duration M, and the like can also be determined according to actual needs, but a certain relationship must be satisfied between them, which can be referred to as one).
For example, the following steps are carried out:
assuming that the value of the time length Z is 30 days, the value of the time length K is 40 days, the value of the time length N is 25 days, the value of the time length P is 5 days, the value of the time length M is 15 days, and the transcoding type is a frame extraction mode with the frame extraction rate of 1/3;
in addition, assuming that the sub-pool 1 is full after 25 days, on the 26 th day, in order to store new video data, the video data of the 1 st day stored in the sub-pool 1 needs to be cyclically covered, and accordingly, the video data of the 1 st day can be transcoded and stored in the sub-pool 2, on the 27 th day, in order to store new video data, the video data of the 2 nd day stored in the sub-pool 1 needs to be cyclically covered, and accordingly, the video data of the 2 nd day can be transcoded and stored in the sub-pool 2, and so on;
in this way, when the actual capacity of the resource pool is fully occupied, 25 days of video data which are not transcoded are stored in the sub-pool 1, and 15 days of transcoded video data are stored in the sub-pool 2, but the capacity actually occupied by the 15 days of transcoded video data is only equivalent to the 5 days of video data before transcoding, so that the purpose of storing 40 days of video data by using the resource pool with the capacity of only 30 days is achieved, and the utilization rate of storage resources is further improved.
In the case that only one sub-pool is included in the resource pool described in the first) or in the case that two sub-pools are included in the resource pool described in the second), after the actual capacity of the resource pool is fully occupied, how to process the resource pool subsequently can be determined according to actual needs, without limitation.
